"The point is ladies and gentlemen that greed, for lack of a better word, is good. Greed is right. Greed works. Greed clarifies, cuts through and captures the essence of the evolutionary spirit. Greed, in all of it's forms - greed for life, for money, knowledge - has marked the upward surge of mankind."

Hello, Humus.
It is very nice to see some progress in OIT. I've just found that OIT by means of atomics could be implemented very fast: see Doron Feinstein Order Independent Transparency optimization on https://sites.google.com/site/doronfeinstein/demos/rendering
It would be interesting to implement his optimized method on your data (or some another realistic data set) to compare BSP traversal with atomics performance.
There is some strong need for robust OIT implementations.
I also have some sort of OIT implementation for motion blur and depth blur cases, it does not work with alpha transparent textures. I have some plan to implement alpha - transparent textures too, (future work), and looking around for state of the art methods to do it in a right way.

this is a clever trick to make sure that all triangles are drawn from back to front. This is required because the scene has transparent elements, so we need to paint the from back-to-front. But in this case, the whole geometry is one mesh, the trick is, that the Index Buffer gets recalculated, so that the order of the triangles in the mesh will match the required back-to-front order.

Note that the index buffer is running on the compute shader, and it only gets recalculated when a BSP plane is crossed (otherwise there will be no change in the required ordering)

Does this technique works for all kind of static mesh and give a big boost in performance because BSP is also used mostly to clip the geometry to win lot of performance in a big static mesh which represent the static part of the scene in one geometry if i'm right. I'm not well experienced with all these kind of optimization so maybe you could give there hints about all that, is it good to use BSP tree for the full static part or have all splitted object and use one octree is better ?

Sure, I have a bunch in the pipeline.

Any new cubemaps in the foreseeable future?
